Design #1
Design #2
Stresses efficiency over learnability and simplicity.
- Makes it as easy as possible for experienced users to accomplish the main tasks. The most-used tasks (recording meals and recording purchased food) can be done right on the home page, and less visible (and thus less learnable) editing styles are chosen because they are faster.
Stresses efficiency over correctness.
- Users make estimates about their caloric intake, rather than calculating calories based on formulae, e.g. (quantity of apple consumed) x (calories in 1 apple). The data collected is less refined than in Design 3.
